ROTARY DISK VALVE.

Application filed March 23, 1927. Serial No. 177,725.

My invention was designed for embodiment in the colloidtrcating apparatus which is the subject matter ot my copending application lSerial No. 177,726 tiled March 23, 1927, for Letters `Patent oli' the United States. However, I do not desire Vto limit myself to such use. In that embodiment, said valve is adapted to alternately connect two kettle tanks with a rotary mill tor comminuting color pastes progressed through said mill from one tank to the other in alternation. In that embodiment; said valve is connected with 'tour conduits, two o1 which lead respectively to said tanks and two ot' which lead respectively to the inlet and the outlet ot said mill. However, the valve structure herein claimed is susceptible o't other uses.

My invention includes the various novel vfeatures et' construction and arrangement hereinafter more detinitely specilied.

In said drawings; Fig. I is a plan viewot a valve structure conveniently embodying my invention.

Fig. II is an inverted plan lView of said valve structure. V

Fig. III is a fragmentary diametrical rsectional view of said valve structure, taken on the line III, III in Fig. I. Y

Fig. IV is an inverted view of said valve structure, with the bottom plate thereof removed to show the arrangement of the semiannular recesses in the valve casing wall.

Referring to Figs. I to IV inclusive; the casing 1 includes a hollow cylinder having two sen'ii-animlar recesses 3Vand 4 'in coaxial relation in its wall, respectively provided with inlet ports 6 and 7 and outlet ports 8 and 9 `for 'fluid temperature controlling means, for instance, steam, whereby the entire valve structure may be heated. Y

Saidvalvc casing 1 is provided with axially opposite end closures 11 and 12; the former having tour ports, respectively 14, 15, 16, and 17, arranged equidistantly in a circumferential series and respectively provided with screw threads 18 'for connection with respective conduits 20, 21, 22, and 23.`v

The other ot said end closures, 12, has the valve bearing '25 incoaxial relation therewith, and the sectoral handle stop flange 26 projecting therefrom in the perimeter thereof in coaxial relation with said valve bearing and having sto ings 27 and 28 at iespective- ,ly opposite ents thereof.

The cylindriform valve body 30 is mounted to rotate in said casing 1 and has the axial stem 31 extending through said bearing 25 and provided with handle engaging means 1ncluning the diametrical slot 32 and pin 33.'

diametrical relation in saidvalve body 30,VA

are connected by the duct extending in said body. rllhe pair of ports 37 and 41 which are also in diametrical relation in Said body, but ytransverse to said iirst pair, are connected by the duct 4G extending'in said body; so that said four ports are thus connected in pairs in crossed relation. i The other four ports in said valve body, to wit, the ports 36,v 38, 40 and 42, which are arranged in alternation with said cross connected ports 35, 37, 39, and 41, are connected in pairs by ducts 48 and 49 extending in said body in parallel relation with said duet 46; said duct 48 thus connecting said ports 36 and 42, and said duct 49 thus connecting said ports 38 and 40.

y The handle 51 is rigidly connected with 'said valve stem 31 by the pin 33 and extends in cooperative relation with said handle stop flange 26, between said stop lugs 27 and 28; so that said valve body 30 may be turned through an arc which is limited to forty-five degrees,

I to alternately connect in crossed relation and in parallel relation the four ports 14, 15, 16, and 17 in said closure 11. In the position shown in Figs. I to IV inclusive; said port `14 is thus connected with said port 16, and said port 15 connected with said port 17 in crossed relation. However. when said handle 51 is moved to the opposite extreme of its range, said port 14 is connected with said port 15, and said port 16 is connected WithA said port 17 in parallel relation. l

The means arranged to circulate a temperature controlling fluid through each ofsaid` semi-annular recesses 3 and 4, include the conduits 53 and 54 respectively connected With said casing inlet ports 6 and 7, and conduits 55 and 56 respectively eonneeted with' said outlet ports 8 and 9. As above contemplated,

said conduits 2O and Q3 may lead torespective y to the precise details of construction, arrangeinent or procedure herein set forth, as it is obvious that various niodiiications may be made therein, Wit-hout departing trom the essential features oi' my invention, as defined in the appended claims.
